Grignon 18 Soybean
Grignon 18 Soybean
95 to 115 days, determinate — The plants are high yielding, reach twenty four inches tall, have purple flowers, and are lightly branched. The beans are red-brown in color and contain 43% protein and 18% oil.
Although the USDA's GRIN database indicates that they received the variety from France, the original log book states that it was collected in Algeria (which had once been a French colony). Regardless of where it was collected, the source of the seed is documented as being from N. Korsakov of the famous N. I. Vavilov Institute of Plant Industry, Leningrad, U.S.S.R. in 1979 and assigned accession number PI 438321. Each packet contains 25 to 30 seeds.
Sow seeds about one inch deep, three to four inches apart. Although you can plant in rows, they can be planted densely and allowed to form a canopy. This will help control weed growth. Soybeans are tolerant of drought and poor soil since they fix nitrogen. They will, however, benefit from fertile soil.
Soybean flowers are perfect (self-fertile) and cross pollination is almost non-existent, making saving seed easy. Allow pods to fully develop and dry on the plants.
